• Context and introductory items
• The following charts reflect Nortels leadership
  in advanced optical networking and continuing
  commitment to development of advanced optical
  networking technologies
• This roadmap is not based on a specific testbed
  but rather on Nortels portfolio of optical
  products/features and that part of Nortels 2B
  annual research budget pertaining to optical
• Currently available or committed to development
• In pre-development phase or the basis of research
  activity
• Key to next three charts
